NOW YOU KNOW enhances natural curiosity and promotes play- based learning by seeking answers to questions preschoolers ask about science, nature and the world around them. Howie and his best friend, a monkey named Baboo, ask a different question in each episode, and then go out into the world to find the answers. Sample questions include: How do fish breathe underwater? Are there holes in the moon? How do snakes move without legs? The series combines puppetry, animation and live-action.
